routine could be used here only that routine has no way of
indicating that the floating point it extracted was invalid (As

something like floating_invalid() to check for an invalid

isn't necessarily a TYPE_CODE_FLT. Consequently, unpack_double
needs to be used as that takes care of any necessary type
conversions. Such conversions are of course direct to DOUBLEST
and disregard any possible target floating point limitations.
For instance, a u64 would be converted and displayed exactly on a
host with 80 bit DOUBLEST but with loss of information on a host
with 64 bit DOUBLEST. */
